Original application filed April 21, 1913, Serial No. 762,548. Divided and this application filed March 28 1914, Serial No. 827,974. Renewed March 1, 1915. Serial No. 11,327.

To (177 whom it may concern Be it known that I, GEORGE ALBERT LYoN, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Buffers for Motor- Vehicles, of which the following is a specification.

The object of my invention is to provide simple and efficient means for securing a resilientbuffer to the side bars of a motor vehicle frame. This object I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which Figure 1 is a plan or top View of a buffer and parts of the side bars of the vehicle frame to which it is applied; Figs. 2 and 3 are side elevations illustrating one method of adapting the buffer to side bars of difierent sizes and shapes; Figs. land 5 are views, partly in section and partly in elevation,

illustrating means for compensating for different depths of side bars; Fig. 6 is a side elevation of a special form of attaching device for the buffer; Figs. 7 and 8 are perspective views, on an enlarged scale, of different members of said device; Fig. 9 is a side elevation illustrating a modified form of washer to be employed in connection with one of the securing bolts for the buffer; Figs. 10, 11 and 12 are side views of diderent washers of this modified type, and Fig. 13 is a transverse section, on an enlarged scale, on the line a.a, Fig. 9.

. The buffer shown in Fig. 1 is similar to that shown in my preceding application Serial No. 762,5-18, of which this is a divi sion, but my present invention is not limited to a buffer of this type but is applicable to buffers generally, consists of two similar but reversely disposed parts, one carried by one side bar of the vehicle frame and the other by the opposite side bar thereof... Each part of the buffer is composed, by preference, of a single rectangular bar of steel'or other resilient metal and of greater width than thickness, the greater dimension of the bar being disposed vertically.

Each part of the buffer comprises'a front transverse member 1 and a rearwardly extending member 2 which is in a plane parallel with that of the side bar of the vehicle frame to which it is to be secured. At the outer end of each transverse member 1 is a rearwardly bent loop 3 and between the latter and the front end of the rearwardly extending longitudinal member 2 is a curved member 4. The transverse front members 1 of the opposite parts of the buffer overlap one another and are preferably held together by means of clips 5 applied thereto. This particular type of buffer constitutes the subject of my application for patent filed April 21, 1913, Serial No. 7 62,548, and constitutes no part of the present invention, nor is the latter limited to a buffer of this type but is applicable as Well to any form of buffer having rearwardly extending members to be secured to the side bars of the vehicle frame.

Each of the rearwardly extending members of the buffer is secured to its corresponding side bar 6 by means of a yoke bolt 7 and a hook bolt 8, the yoke bolt 7 embracing the bar 6 and having legs passing through openings in the member 2 and threaded for the reception of securing nuts 9, as shown in Fig. l. The hook bolt 8 overlaps the top of the bar ti and passes down through an eye at the rear end of the member 2 of the bufier, this portion of the bolt being threaded at its lower end for'the reception of a securing nut 11, as shown in Figs. 2, 3, 4, and 5. By this means a threepoint bearing is provided, the front and rear bearings being on the top face of the side bar 6 and the intermediate bearing being on the bottom face of said bar, whereby, when the bolt 8 is tightened, a leverage is exerted which causes the upper and lower legs of the yoke bolt 7 to press firmly against the top and bottom of the bar 6, the member 2 of the 'bufi'er being therefore securely confined to said bar, and the contact side of said member Q'being held firmly against theside of the bar by reason of the clamping action of the yoke bolt 7.

That portion of each rearwardly extending member 2 of the bufier which carries the yoke bolt 7 is inclined in respect to the front and rear portions of said member, as shown in Figs. 2 to 5, so as to permit of the diagonal disposition of said yoke bolt onthe side bar 6 and thereby provide for the application of the buffer to side bars of different size and shape, as shown in Figs. 2 and 3, while still maintaining the vertical disposition of the longer axis of each of the transverse members 1 of the buffer, as there shown.

It is sometimes advisable to provide one leg of the yoke bolt 7 with an eccentric sleeve or washer 12, as shown in Figs. 4 and 5, this sleeve being rotatable on the leg of the bolt and being, by preference, of polygonal form, and presenting different surfaces at different distances from its bore, whereby, in applying the bufier to a shallow side bar 6, one of the higher faces of the washer may contact with said bar, as shown in Fig. 4,

while in applying the buffer to a deeper side bar one of the lower faces of the washer may be utilized, as shown in Fig. 5.

When the side bars of the vehicle frame are, as shown at 6* in Fig. 6, in the form of channel bars with upper and lower projecting flanges, the hook bolts 8 and the rear horizontal portions of the members 2 of the buffer may be omitted, and the upper and lower legs of the yoke bolt 7 may be provided, respectively, with sleeves 13 and 14, as shown in Figs. 6, 7 and 8, the sleeve 13 which is applied to the upper leg of the bolt having a hooked lug 15 for engaging the upper flange '16 of the side bar and the lower sleeve 14: being, by preference, of the eccentric polygonal type and having on each of its faces a hooked lug 17 for engaging the lower flange 18 of the side bar, depending upon which face of the sleeve is adjusted for contact with the lower face of said bar. By

this means the rearwardly extending members 2 of the buffer are readily cpnfined in their proper relation to the side bars 6 while at the same time, owing to the fact that the sleeves are free'to turn on their respective legs of the bolt, adjustment of the buffer to its different positions on theframe is permitted, the hooked lugs 15 and 17 adapting themselves to the angles presented by the upper'and lower fianges'16 and 18 of the bar 6 in the different positions of adjustment of the buffer on the latter.

Instead of using an eccentric polygonal sleeve 12 or 14 a series of sleeves 20 may be employed, each having a different degree of eccentricity, as shown for instance in Figs. 9, 10, 11 and 12, and the rearwardly extending member 2 of the buffer may be disposed either on the inside of the side bar of the frame member, as shown in Figs. 2, 3 and 9 or on the outside of the same, as shown in Figs. 4 and 5, depending upon which side of the member 2 the eye 10 is disposed.

1. A motor vehicle bufier having an attaching member lying alongside of a side bar of the vehicle frame and secured thereto by means of a yoke bolt, said attaching member having an inclined portion for engagement with said yoke bolt, whereby the lat-- ter can be disposed diagonally in respect to the side member of the frame.

2. A motor vehicle bufier having an attaching member whereby the same is secured to a side bar of the vehicle frame, a'securing bolt for said attaching member, and an eccentric sleeve applied to said. bolt and serving to compensate for difierent depths of side bars.

3. The combination of the attaching member of an automobile bufier, and means to secure said member to a side bar of the vehicle frame, said means having two points of bearing on one face of the bar and one on the opposite face of the same, said single bearing constituting a fulcrum and one of the opposite bearings being adjustable so as to exert a leverage on the other of said 'bearings.

4:. The combination of the attaching member of an automobile buffer, and means to secure said member to a side bar of the vehicle frame, said means including a device which engages the top and bottom surfaces of said side bar, and means for engaging the bar at another point and causing the attaching member to act as a lever of which one of the other bearings is the fulcrum.

5. The combination. of the attaching member of an automobile buffer, and means to secure said member to a side bar of the vehicle frame, said means including a device which engages the top and bottom surfaces of said side bar and is provided with adjusting means, said attaching member also having an adjustable bearing on the bar some distance from the first two bearings, wherebv the attaching member constitutes a lever of which one of the first two bearings is the fulcrum.

6. A motor vehicle buffer having an attaching member lying alongside of a side bar of the vehicle frame, a yoke bolt for clamping said member to the side bar, said yoke bolt being disposed diagonally in respect to said side bar, and means for locking said yoke bolt in such diagonal relation.

In testimony whereof, I have signed my 1 name to this specification, in the presence of KATE A. BEADLE, HAMILTON D. TURNER.
